Cyprian of Carthage, Three Books of Testimonies Against the Jews III.40: That there is given to us an example of living in Christ

In the Epistle of Peter to them of Pontus: “For Christ suffered for us, leaving you an example, that ye may follow His steps; who did no sin, neither was guile found in His mouth; who, when He was reviled, reviled not again; when He suffered, threatened not, but gave Himself up to him that judgeth unrighteously.” Also Paul to the Philippians: “Who, being appointed in the figure of God, thought it not robbery that He was equal with God; but emptied Himself, taking the form of a servant, He was made in the likeness of man, and was found in fashion as a man. He humbled Himself, becoming obedient even unto death, and the death of the cross. For which cause also God hath exalted Him, and hath given Him a name, that it may be above every name, that in the name of Jesus every knee should be bowed, of things heavenly, and earthly, and infernal; and that every tongue should confess that the Lord Jesus Christ is in glory of God the Father.” Of this same thing in the Gospel according to John: “If I have washed your feet, being your Master and Lord, ye also ought to wash the feet of others. For I have given you an example, that as I have done, ye also should do to others.”
